"Catch-all email" bug in G Suite

Finally I found out why I stopped receiving Dreamwidth notifications by email.

The reason for my email problems was that "catch-all email" functionality stopped working in my "G-suite" account (AKA "Google Domains") on my @dennisgorelik.com domain.

"Forward email to:" radiobutton was still selected correctly:
https://admin.google.com/dennisgorelik.com/AdminHome?hl=en_US#ServiceSettings/service=email&subtab=filters


But actual "catch-all email" functionality -- simply did not function in my @dennisgorelik.com domain.
Emails to addresses like somerandomemail@dennisgorelik.com -- simply bounced:
=============================
Error Icon Address not found
Your message wasn't delivered to somerandomemail@dennisgorelik.com because the address couldn't be found, or is unable to receive mail.

The response was:
The email account that you tried to reach does not exist. Please try double-checking the recipient's email address for typos or unnecessary spaces. Learn more at https://support.google.com/mail/answer/6596
=============================



To fix this problem - I selected "Discard the email" radiobutton and then again selected "Forward email to:" radiobutton.
That "deselect -> select again" trick fixed the issue ...
... kind of. I still need to make sure that email senders still send emails to my addresses.
If emails bounce - it is a common practice [among email senders that are sending a lot of emails] to stop sending emails to non-deliverable email.


Some other effects of this bug:
- I did not receive Facebook notifications and, because of that, visited Facebook ~5 times less frequently.
- I missed some bank emails (fortunately not very important yet).
- Missed email from a car salesman that I asked him to send.
- I am probably missing some other emails, but I do not know which emails I am missing...
